My understanding of my family’s religion was that we didn’t have to go to church if we didn’t want to and that our belief in God was tenuous at best. I grasped the seventh principle, “the interconnected web of all existence,” and I understood the humanist tradition in a vague sense, but the truth is I didn’t think about Unitarianism all that much. I hadn’t been to church in months. That Sunday, my brother and I went with our mother. We sat five rows back, near a woman named Tamsin Brodhead. Tamsin was tall like a basketball player, and very serious. It was an unspoken rule in the congregation that we should never mention her brother to her. David Brod was the lead singer in a once popular, now aging rock band, and no matter how much we had been prepared it was still a shock to see him there.
